If Days doesn't or didn't listen to fanbases then why do fanbases still collect money to send in "gifts" that symbolize their couples or participate in letter writing campaigns?

I mean it has to have worked for fanbases at least a couple of times or these groups wouldn't keep doing what they are doing would they?

In a futile attempt to get TPTB to listen? I can't think of a specific time when any campaign I have been involved in worked so to speak. Mostly, I think, fans do it to show appreciation to the actors and writers if they do something you like and you want to see more of it. Rarely do you find out if it "worked".
